Abstract: Product reviews mining is mainly used to extract the information from amount of consumers’ comments on the Web，and then the consumers’ positive or negative semantic orientation on a product’s parts or function is gotten.The existing product reviews mining do not deal with either hyponymy features or the same feature described in different words.This article firstly mines the manufacturers’ specification files to get the specification features and their hierarchies，and then uses the Bootstrapping weakly supervisory method to extract the consumers’ describing features from the website editors’ evaluating articles and gets its hierarchies with specification features.This method has been used in mobile phone features research.The experiment shows that the hierarchies among a product’s features extracted in this way are efficient.
